The Sentence Corpus of Remedial English was updated and moved to a new website earlier this month: http://www.score-corpus.org. After following the link, there is a button in the top right corner of the page to switch to English.
The tools (Pattern Browser, Concordancer, Quiz Generator) seem to be the same, but it appears the corpus itself has expanded. The new website is much more comprehensive in the information it provides, including pages for things like SCoRE-related publications and user guides in both Japanese and English (there used to only be a Japanese language user guide). There is even a page where users can submit example sentences that may be included in future updates of the corpus.
Very good to see this project developing and continuing.
